Project Hail Mary by Andy Weir

It is hard to describe what happens in this book without giving it all away, so I am going to be brief. The first thing is that this book, much like the author's previous book, The Martian, is largely a system based novel that a character driven one, and as such, there are a lot of descriptions of what is happening rather than why they are, and there are only two characters and one human. What I can say is that tells the story of Ryland Grace, a high school science teacher who wakes up alone on a spaceship in a different star system with no memory of how he got there. He quickly figures out that he’s been sent on a mission to save our solar system from a microorganism called the Astrophage, which is essentially eating our sun. If Ryland doesn’t succeed, the Earth will enter a new ice age that kills billions of people. There are many twists and turns and it adds up to a very enjoyable read.
